Ragweed Season in Houston (2026): Daily Allergen Support | OLLEREG
Houston · Ragweed & Fall Allergens

Houston's ragweed season starts mid-August.

Daily allergen support, built around your allergens and reviewed by a physician. Two sprays in the mouth, every morning. Mid-August to first frost is months, not weeks, so the routine starts now.

Start my 2-minute intake Takes about 2 minutes. No account needed to start.
Formulated by Dr. Dat Tran, MD, FAAAAI, a board-certified allergist whose Houston practice has treated 1,000+ patients and counting.

Three steps. Then it lives on your counter.

1

Tell us your triggers.

The 2-minute intake maps what you actually react to, from ragweed and oak to grass and mold.

2

A physician reviews.

Every intake gets a physician's safety review before your routine ships. That review is built into how OLLEREG works.

3

Two sprays in the mouth, daily.

It lives on your counter, not in your schedule. Two sprays each morning, shipped to your door every month.

This is a routine that builds over time.

OLLEREG is ongoing daily support, not a quick fix. Here is the honest arc most people follow.

Month 1

A new morning habit.

Two sprays in the mouth. That is the whole routine. The goal this month is simply doing it every day.

Month 3

The window to watch.

Real changes tend to show at 3 to 6 months as your body adjusts. This is when people usually start to notice a difference.

Month 6

Part of your morning.

By now it is as automatic as brushing your teeth. Ongoing support you keep going, season after season.

Ongoing support, not a quick fix.

A season of pills, or two sprays a day.

Same mornings, a different routine. Here is the honest contrast.

The default

A season of pills.

Every morning, another dose to get through the day. When the bottle runs out, you are back where you started. It manages symptoms for the day and asks you to repeat it, indefinitely.

The OLLEREG routine

Two sprays a day.

A daily routine that supports how your body responds to allergens over time. Doctor-formulated, physician-reviewed, and shipped to your door each month. Two sprays in the mouth, then on with your morning.
